BLOCK.

Application filed March S1923. serial No, 622,597.

To all whom t 'may concern.

Be it known that I, LUTHER B. ONEAL, a citizen of the United States, residing at Pensacola, in the county of Escambia and State of Florida, have `invented new and useful Improvements in Blocks, of which the following is a specification.

This invention relates to paving blocks, and has for its object the provision of a wooden paving block formed with a recess in the bottom thereof to receive a portion of the concrete foundation upon which the block is arranged so that the portion of concrete received by the recess forms a lug for locking the block to the foundation and preventing buckling of the block when the latter is in use.

In carrying out the invention, it is my purpose to provide the block with a recess which opens at one side of the block, so that the blocks, when arranged side by side, the adjacent blocks will have their recesses open` ing into each other in a manner whereby the blocks are locked together as well as to the foundation by the concrete received by the recesses thereof.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings `forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a vplan view of a portion of a pavement.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is aview similar to Figure 2 showing a different arrangement of the 'blocks for the purpose of locking the blocks together.

Figure 4 is a perspective view of one of the building blocks.

Figure 5 is a sectional view taken on the line 5-5 of Figure 4.

Figure 6 is a transverse sectional view through a plurality of blocks associated.

Referring to the drawings in detail, 10 indicates a wooden paving block which may vary in size and configuration without departing from the spirit of the invention. The particular characteristic of this block resides in the provision of a recess 11, which recess is formed in the bottom of the block between the ends thereof, but which recess opens at one side of the block as illustrated. The recess is preferably of dove tail formation Vand semicylindrical in contour but it is to be understood that the size and the shape of the recess is not a matter of moment, and can be varied within the scope of the appended claims and without departing from the spirit of theinvention. The recess is provided to receive a portion of the concrete upon which the block is arranged, which forms a lug for locking the block fixed relative to the foundation upon which it is laid, and at the same time preventing buckling of the block under any and all circumstances.

The block can be arranged upon the concrete foundation 12 in a manner so that the blocks are locked one to the other, in addition to being locked to the foundation as shown in Figure 3 or they can be laid so that each block is locked independently of the foundation as shown in Figure 2. When it is desired to lock the blocks one to the other, the blocks are so laid that the recess of the adjacent blocks communicate with each other, and unitedly denne a large pocket to receive a portion of concrete foundation as shown in Figure 3. Manifestly in this inst-ance, the one lug formed by the concrete positioned in the recess serves to zlock the blocks together as well as to hold them fixed to the foundation. If it is desired to lock the block independently to the foundation 12 they will be arranged in the manner shown in Figure 2 that is each block is laid so that the recesses will open or extend in the same direction as the recess in the adjacent block.

While it is believed that from the .foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, I claim: i

1. In a pavement, a plurality of paving blocks adapted t-o be arranged side by side in contacting engagement upon a concrete foundation, and each block having a recess in the bottom thereof opening at one longitudinai edge and the recess of the adjacent blocks connecting With each other and nnitedly defining a circular pocket of dovetailed formation in cross section, and adapted to receive a, portion of the concrete toune dation *for the purpose specifiedn 2. A paving bock of elongated contour having a semi-circular recess formed in the bottom thereof and opening at one longitudinal edge of the block, the curved Wall l0 of said recess being inclined to afford the recess a substantially dove-tailed configura tion in cross section.

In testimony whereof I affix my signature LUTHER B. ONEAL
